You're demanding a scenario that needs not be there for the event to take place. You don't need to remove interior walls to place explosive charges, especially when the core of the structure in situated next to the elevator shaft. The video shows how they would have done it. Everyone believes in gravity. Funny how building that were built tough to withstand just about anything crumbled to dust when a plane crashed into it. To be more specific, skyscrapers are engineered to withstand such elements that it may possibly encounter such as plane crashes and destructive storms. You're going to resign yourself to a belief that jet fuel fire brought down an entire ... no wait... three skyscrapers in one day? This has never happened before... ever... until 9/11. Maybe if you understood physics you wouldn't have to resign yourself to trying to boost yourself up in a field you know nothing about to try to get the upperhand. Cell phone calls from the plane?! At that altitude and position - people were getting cell phone calls?! This is impossible and you can't do or say anything to make it so.
